-It will be observed thatthere are included in the body ofthe diewblock,lnail-holding openings l62, 62,-co`ming'at therearjof the heel-seat andwhich are notvariablein position. This is due to the fact' that, for allsizes of shoes, the relationl to these openf ings is unchanged.

The drivers 18 aren respectively lixedin vcarriersy 64 independentlymovable in horizontal ways 66 in the driver-plate 16, these carriers andtheir supports-being vertically alined with the slots 22 land 24, sothat in insole.

To the inclination of the openings 46 thedrivers may adapt themselves by their own resilt ence.
